AUXILIARY CONSTANT-FUEL-SUPPLY APPARATUS FOR. AUTOMQBILES.

Application led November 20, 1915.

To all whom t may concern:

Be it known that I, JAMES NV. IVELLING- TON, a citizen oftheUnitedStates, residing Y at 802 First St., Jackson, county of Jackson,State of Michigan, have invented certain new and useful Improvements inAuxiliary ConstantFuelSupply Apparatus for Au tomobiles, of which thefollowing is a specification.

This invention relates to improvements 1n an auxiliary constant fuelsupply apparatu of an automobile. Y

. operation will definitely appear from the detailed description tofollow.

I accomplish the objects of my invention 'by the devices and meansdescribed vin the following specification. The invention is clearlydefined and pointed out in the claims.

A structure whichis a preferred embodiment of my invention is clearlyillustrated in the accompanying drawing forming a part of thisspecification, in which:

Figure I is a dotted side elevation of an automobile showing thelocation of my auxiliary gasolene tank and its connection to the supplytank in the rear of the car and to the carbureter.

Fig. II is a detail vertical section through the auxiliary supply tankand feed means showing the operating mechanism, all of which constitutesa single unit.

Fig. III is a detail vertical section showing the connection of the Hoatarm to the switch operating arm, taken on a line corresponding to thesection line 3 3 of Fi g. II.

Fig. IV is a detail vertical section of a modification of my auxiliarysupply gasolene tank and feed means wherein the pump Specication ofLetters Patent.

and motor are on a mounting separate from that of the tank and switch.

In the drawing, similarreferenc-e characters referto similar partsthroughout the several views, and the sectional views are taken lookingin the direction of the little arrows at the ends of the section lines.

1 is an automobile, on the dash of which,

, preferably within the hood, is mounted my auxiliary gasolene tank 2which connects by supply pipe 3 to the carbureter 1, the latter being ata lower level than that of tank 2. 5 is the auxiliary tank cover. Pipe 6extends from main gasolene tank 7, here shown situated in the rear ofthe car, to `a pump connection on the cover. Cover 5 integrallyconstitutes the motor base 8 and the pump cylinder 9. From one side ofcylinder 9 runs the inlet passage 10 which connect-s to pipe 6. A ballcheck valve 11 is situatedso as to permit the flow of gasolene towardthe pump. On the other side of cylinder 9 is the pump discharge passage12 which delivers to the tank 2 by the ball check valve 13. Within thepump cylinder 9 is the pump plunger 14 reciprocated by an electric motor15 and its connections. On the base 8 is mounted the electric drivingmotor 15 which connects by pinion 15 to the pump driving gear 16 securedto the gear shaft 17, the journal bearings of shaft 17 not being shown.On shaft 17 is also mounted the pump eccentric 18. Within the hollowplunger 14 is disposed the pump spring 19 which maintains the plunger inoperative contact with the eccentric 18. There is no eccentricring. Theeccentric is a cam..

Within the tank 2 is the float 20 conrl'ected by a float arm 21 to oneend of float arm rock shaft 22. Where oat arm rock shaft 22 passesthrough cover 5 any leakage is prevented by gland 24, the cover beingpocketed at this point as shown in Figs. II and III to accommodate thestructure.

On cover 5 is mounted the motor switch consisting of the movable arm 25and the stationary arm 26. Arm 25 is pivoted at 27 and forked at 25 and25" -so as to permit the actuating arm 23 to play between the fork arms.The switch controls the circuit 28 to the motor 15 from the storagebattery 29 of the car or any other source of electric energy. It isevident, therefore, that when the ioat is at its highest or lowest pointthe switch will be respectively opened or closed by the action of arm23,.and when closed the motor rotates eccentric 18 which reciprocatesplunger 14J thus pumping gasolene from supply tank 7 to auxiliary tank2, the check valves permitting the flow of gasolene in one direction.The supply of gasolene is then gravity fed from tank 2 to the carbureterand the supply is kept constant by the elect-ric pump means.

A modification of my structure is shown Other parts of this modificationare the samev as those shown in my preferred structure. It is seen bythis, that although the auxiliary tank will have to be mounted at alevel higher than ythat of the carbureter, the pump with lits drivinmechanism, may be placed in any part o the car, but will alwaysbeautomatically controlled and operated.

, Having thus describedk my invention, what I claim as new and desire tosecure by'Letters Patent is:

1. In a constant fuel supply system, the combination of an auxiliarytank, a pump for the filling of said tank, an electric motor foroperating said pump, a float within said tank, a float arm rock shaftJournaled in thel tank cover, a float arm connecting the float, a switchhaving a forked movable arm, a switch actuating arm -cover for fillingthe same from theY mainVY supply, an electric motor for operating saidpump, an electric circuit and source of supply, a float within the saidtank,connec tions from said float to control the said cir` cuit all ofwhich are disposed on said cover as a base,`coacting for the purposespecified.

3. In a constant fuel supply system, the combination of an auxiliaryfuel tank provided with a detachable cover ,hav-ing a fuel passageformed therein for discharging fuel into said `auxiliary tank, a pumpconnected with said fuel passage and adapted to force'fuel therethrough,means for driving said pump, and means controlled by the level of thefuel in said auxiliary tank for controlling said driving means, saidpump driving means and controlling means beingmounted upon said cover.

In witness whereof, I vhave hereunto set my hand and seal in thepresence of two witnesses.
